Neutropenic enterocolitis is a frequent autopsy finding in adult patients with acute leukemias. The predisposing factors other than neutropenia are not clear. There are also contradictions about treatment. Therefore, this entity still presents a diagnostic and therapeutic dilemma for clinicians. This retrospective study was performed to determine the incidence of neutropenic enterocolitis in adult leukemic patients, to examine the possible risk factors, clinical characteristics and treatment outcome. The pathogenesis is also discussed considering clinical and laboratory findings of the patients. The incidence of neutropenic enterocolitis was 6.5% for acute myeloid leukemia and 4.6% for acute lymphoblastic leukemia. The mean absolute neutrophil count at diagnosis was 48/mm3 (median: 0/mm3). The median duration of severe neutropenia (absolute neutrophil count < or = 500/mm3) on follow-up before the diagnosis was 32 days. Thirteen out of 20 patients had received antineoplastic drugs within the last 12 days, but 2 had not. Fourteen patients had signs of peritoneal irritation and 3 of them underwent surgery. The others received supportive measures, i.e. bowel rest, intravenous fluids, combinations of wide spectrum antibiotics, transfusions, hemodynamic supports and nasogastric decompression, if necessary. All 3 patients who underwent surgery survived, whereas only 1 of the 11 who received other treatments did. Six patients without signs of peritonitis were treated with antibiotics and the mentioned supportive measures. Four survived, but the others died due to sepsis. In conclusion, considering some recent reports that stated good outcome with conservative measures in the presence or absence of peritonitis, there is still debate regarding the optimal choice of treatment. The importance of early diagnosis cannot be overemphasized. Signs of peritoneal irritation indicate a life threatening condition. Surgery can be performed successfully in such patients. Long duration of neutropenia may be an important risk for neutropenic enterocolitis.

Neutropenic enterocolitis (NE) is an unusual complication of neutropenia. Its presentation is dramatic, treatment is controversial, and the outcome may be devastating. The available literature about this entity is mainly case reports and autopsy studies. We have recently performed a celiotomy on a patient who developed sepsis and an acute surgical abdomen three days following chemotherapy and radiotherapy for a metastatic adenocarcinoma with no known primary tumor. At surgery he was found to have a boggy right and recto-sigmoid colon with a grossly normal transverse colon. Intraoperative colonoscopy revealed mucosal ulceration and necrosis extending from the dentate line to the cecum. A total abdominal colectomy, closure of the rectal stump, and an ileostomy was performed. Postoperatively, the patient recovered from the abdominal septic process only to succumb to multiple system organ failure secondary to pulmonary sepsis. Upon review of the literature, we found 65 cases of NE that were suspected or diagnosed in the antemortem state and confirmed at surgery or autopsy. In this review, we intend to analyze these case reports, summarize the salient features of the disease and outline the optimal therapeutic approach.

Neutropenic enterocolitis (NE) is a serious complication in neutropenic patients. Once exclusively thought to be found in patients with leukemia and lymphoma, it is now being seen with increased frequency during bone marrow transplant, chemotherapy for solid tumors, and in patients suffering from acquired immune deficiency syndrome and cyclic neutropenia. The pathophysiology of NE is not completely understood, but unquestionably involves neutropenia, mucosal barrier damage, and infection resulting in a necrotizing process of the bowel wall. The cecum, ileus, and ascending colon are most commonly involved. Initial symptoms are usually nonspecific abdominal pain and fever. Localized, severe right lower quadrant pain, sepsis, and bowel perforation may rapidly develop. Once considered a fatal complication, the outcome for the child with NE has improved with better diagnostic imaging techniques and antibiotics. Most children can be successfully managed conservatively with early introduction of broad-spectrum antibiotics and supportive care. However, a significant number will need surgical intervention. Nursing care of these children requires knowledge of the disease process, excellent clinical assessment skills, and a compassionate, family-centered approach.

Neutropenic enterocolitis (NE) is an unusual acute complication of neutropenia, most often associated with leukemia and lymphoma which is characterized by segmental cecal and ascending colon ulceration that may progress to necrosis, perforation, and septicemia. We present a case of neutropenic enterocolitis in a patient with non-small-cell lung cancer who received docetaxel and flavopiridol as part of a phase I clinical trial and review cases in the literature where docetaxel was involved. Given the increased use of docetaxel and other taxanes in the treatment of advanced lung cancer, physicians should be aware of this potential toxicity of therapy.

Neutropenic enterocolitis is a life-threatening gastrointestinal (GI) complication of chemotherapy most often associated with leukemia or lymphoma. Early recognition and treatment are essential for survival. The management of neutropenic enterocolitis is controversial. Neither prospective nor high-quality retrospective studies concerning medical or surgical therapies are available. Treatment approaches have been derived mostly from small case studies and retrospective reports. Therefore, a uniform management strategy cannot be recommended. The best strategy appears to be an individualized approach to each case given the wide spectrum of presentation. There is general agreement that early management should be conservative and should consist of bowel rest, intravenous fluid administration, total parenteral nutrition, broad-spectrum antibiotics, and normalization of neutrophil counts. Surgical intervention is warranted in the setting of perforation, obstruction, clinical deterioration suggestive of uncontrolled sepsis, and persistent GI bleeding despite correction of cytopenias and coagulopathy.

Neutropenic enterocolitis is a severe and potentially life-threatening complication that may affect patients undergoing chemotherapy for acute leukemia or lymphoma. These patients may develop systemic sepsis through bacterial or fungal translocation across the intestinal wall. In many cases neutropenic enterocolitis is confined to the cecum, but the entire colon is sometimes involved. Most patients are treated conservatively because an improvement occurs when the absolute neutrophil count rises. However, a surgical approach consisting of resection of the colon may sometimes be necessary, even in patients with complete aplasia and a high risk of complications. The right time to perform surgery is hard to define. Intestinal wall thickness, evaluated by ultrasound, is an important prognostic factor which could act as a guide to surgical indication. We analyze a case of neutropenic enterocolitis which occurred in a patient with acute myeloid leukemia during chemotherapy and we suggest that, as well as intestinal wall thickness, hemodynamic worsening should be considered an indication for surgery.

Neutropenic enterocolitis, also known as typhlitis or ileocecal syndrome, is a rare but important complication of neutropenia associated with malignancy. It occurs as a result of chemotherapeutic damage to the intestinal mucosa in the context of an absolute neutropenia, and can rapidly progress to intestinal perforation, multisystem organ failure, and sepsis. Presenting signs and symptoms may include fever, abdominal pain, nausea, vomiting, and diarrhea. Rapid identification by emergency physicians and timely, aggressive medical and/or surgical intervention are the cornerstones of survival for these patients.

Neutropenic enterocolitis (NE) is a deadly ileocecal-based disease seen in patients with a recent history of chemotherapy. As histology is not included in the current diagnostic criteria, the pathologic features of NE are poorly understood. We undertook a multi-institutional study of NE, and report helpful clinical clues, such as immunosuppression (n=20/20), recent chemotherapy (n=17/18), neutropenia (n=16/18) gastrointestinal symptoms (n=19/19), abnormal imaging studies of the cecum/right colon (n=11/14), and positive microbiological studies (n=13/15). Fever (n=9/15) and sepsis (n=8/16) were also common. Pathologically, the cecum/right colon was always involved (n=17/17), but findings were identified in other bowel segments as well. NE lesions consisted of patchy necrosis (n=18/20), infiltrating organisms (n=17/20), hemorrhage (n=15/20), ulcer (n=15/19), edema (n=15/20), and depletion of inflammatory cells (n=15/20). Seventy-nine percent (n=15/19) of patients with histologically confirmed NE died: 47% (n=7/15) of these deaths were attributed to NE and the remainder to the patients' underlying conditions. Importantly, we observed a clinical diagnostic discordancy rate of 35% (n=9/26): 15% (n=3/20) of histologically confirmed NE were clinically unsuspected, and 26% (n=6/23) of clinically suspected NE represented a different disease process. Alternative diagnoses included unspecified colitis, infection, graft-versus-host disease, relapsed malignancy, mycophenolate injury, appendicitis, and ischemia. The causes of death in patients with NE mimics included unrecognized appendicitis and unrecognized graft-versus-host disease. To improve diagnostic accuracy, we propose that histology be required for a diagnosis of "definitive NE," with other clinically suspicious cases reported as "suspicious for NE" until all other possible diagnoses have been reasonably excluded.
